Forces and Newton's Laws

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time. It can be a change in speed or direction.

Front

Define inertia.

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. For example, 30 mph west is a velocity.

Front

What is speed?

Back

Speed is the distance traveled per unit of time, regardless of direction. For example, 65 mph is a speed.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is a force?

Back

A force is a push or pull on an object that can cause it to accelerate, change direction, or change shape.

Front

What is Newton's First Law of Motion?

Back

An object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed as F = ma.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
